Belts are still in car, prob will leave em.

Just curious really, I mean even racing with full legit NHRA stuff (5pt, helmet, bar) seems like it won't help with neck whiplash if hitting something frontal hard.

This is true and anything can happen but my thought would be this is less likely to occur. Anything is possible, but I would think lower probability. I guess its up to you how safe you want to be.

Belts and bars were never intended to control head movement in an accident. Bars are for preventing roof crush and intrusion in a wreck and the helment is meant to try to prevent some level of brain scramble in an impact.

If you want to control head movement the only way is with a supplimental restraint.

I understand that, my question is posed towards why its not a huge issue to NHRA etc

How high is the risk for a front or rear impact? Its not like you are turning or dealing with cars hitting the brakes.

He drives through Lakewood every now and again....:nick:

Side story, coming home on Weds, in gf's civic and coming through Little Israel.. some lady in oncoming lane (in a minivan) decides to suicide abrupt left turn and cut us off, and then proceeds to rock the curb, poor poor tie rods, tire, wheel.. etc..

I laughed at the proving of stereotypes.

/off topic

then he needs an exo-cage for, um, crowd control

Driving through laywood is simple, stick to the outskirts unless its friday nite n saturday day haha

I know this is not srs but does he plan on wearing a helmet, hans, and harness every time he drives the car? In the sport of drag racing, I'm just not sold on the need for a hans at this power level AND level of "competition"

Nope. Again, I am asking in theory about the risks of 5pt harness vs 3pt OE belt restraint.

Interesting subject as there is little or no actual testing done to show one is an improvement.

no testing of what? HANs devices?

Restraints and roll cages/bars.

At least that I can find.

Both belt types will result in whiplash. Probably one of the more common reported injuries that I see along with air bag burns.

that you can find is key, at least if I understand your comment correctly. I'd think there has been a lot of crash testing that results in the various sanctioning bodies rules. I don't think they generally make that info public.

Yes, that is my comment's point.

I am not arguing HANS, 5pt harness, bars,cages etc provide a ton of protection, but I was looking for something more than, "The sanctioning body says you need it, deal with it"

Just interesting that something so important, is so hazy and vague.

NASCAR did they did a lot of research post-Earnhardt. I think the OEs were involved. that is how they changed their rules, including HANs. Guys sure get out of wicked wrecks in those cars.

I guess you have two choices. have faith in those rules or ignore them because you want to.

HANS is for 7:49 and quicker. 9.00 to 7:50 is a neck collar. The 5 point will hold you in place if you roll over. you can slide out a standard 3 point in a rollover ( I've done it )

That is not my point in all this.

I am looking at how safety systems sanctioning bodies react when subjected to normal driving scenarios.

I meet tech (sorta) as of now, but I am still rocking a heavy helmet and a fixed body, just seems odd that neck issues are not prevalent in this combo.

I misunderstood. But I very much doubt you will get the answer you are looking for.

Multi point harnesses have been proven safer many times in accidents. That's why racing went to them years ago. Also, as long as the system can be clipped and unlocked with one hand it is ADA compliant and considered legal for a passenger vehicle.

On the other hand a roll bar without a helmet is a very real danger in an accident. Tubes are skinny and present a small focal point so even a seemingly light impact will cause more damage than flat or more broadly curbed surfaces.

The SCCA did a writee up about this many many years ago. Can't find it online and I am not in the mood for searching through 20+ years of magazines to find it.

I know, it frustrates me having to go off of "this is what is required, therefore it works" mindset. I can't tell customers that, why can the NHRA get away with it.

Need evidence, studies etc.

I digress.
